DSNAODV: Detecting Selfish Nodes based on Ad hoc On-demand Distance Vector routing protocol

In mobile ad hoc networks (MANETs), innumerable intermediate nodes interchange information without the need for infrastructure. In these networks, nodes depend upon each other for routing and forwarding packets, and communication among them is very important. Forwarding packets consumes network bandwidth, local CPU time, memory, and energy. Therefore, some nodes might intend not to forward packets to save resources for their use that called selfish nodes. The destruction of basic action of the network can occur due to this selfish behavior of the node. So, in this paper, we focused on dropper misbehavior for data packets and route request packets. For detecting this kind of nodes in this paper, we improved the ad hoc on-demand distance vector (AODV) routing protocol and proposed a new routing protocol for detecting selfish nodes. The performance analysis shows that the DSNAODV (Detecting Selfish Node based on Ad hoc On-demand Distance Vector routing protocol) protocol can improve the packet delivery ratio and use less energy compared to AODV and EBTS protocols.
